To all whom it may concern:

Be it known that l, WALT-En P. Moreen a. citizen of the United States, rcsiding'et Chicago, in the county of Cool; and State of Illinois, have invented certain new and use ful Improvements in Vertically(lorrugeted Sheet-Metal Car Ends of which the following as e specification,

The invention relates to the construction of railway cars, more particularly to corrugeted sheet metal end structures for reilwary cars, and one oiithe principal objects of the invention is to provide a vertically corrugated car end in which the corrugations are formed of smart cross sectional area. at points above the lloor of the our and structure, thereby giving the end its greatest strength to resist the thrusts and pressures of the cargo, for example, at the place where strength is particularly required.

- The lnvention has for further olnects such other new and improved constructions, a1

rangeinents and devices relating; to corrngated sheet metal oer ends as will he herein-- after described and claimed.

The invention is illustrated as einhodied in a sheet motel car end for gondola cars. The same principles of construction might be applied to end structures for different types of cars.

In the drawing, v

Figure 1 shows, in elevation, the end of a railway car constructed in accordance with my invention.

Fi 2 is a sectional plan on line 2-42 of Fig. 1, and

Fig. 3 is a vertical sectional view on line 3-3 of Fig. 1. 1

Like cheracters'ot reference designate like parts in the several figures of the drawing.

Referring to the drawing, the under frame of the oer is indicated at 10, ll is theflooring a d 12 the side walls. 13 represents the side stokes. The end of the oer, in the embodiment of the invention herein shown, consists preferably of a single sheet of steel 14 formed with e plurality of vertical corrugetions these corrugations are deepest and wides, at points shove the floor of the car but below the horizontal center line of the end. The corrugations teper toward their extremities and die out within the edges of the sheet. 'lhis arrangement gives i Elctters Eeteut.

Patented [this recess. Divided end this application filed June 5,

the end structure maximum strength along at line where the greatest strength is required. It will be understood that ends of railway freight cars, of all types are subjected to thrusts and pressures from the lcding due to inertia when the trein These thrusts and pressures are greatest the lower half of the end d ere finest likely to he destructive when exer" against the end structure along a. line shove the floor approximately at the place of greatest cross sectional area of the corrugations as shown in the drawing,

To still further strengthen and rigidity e end structure along this line it preferably T their deepest point as indicated et it'll. The end sheet M is preferably formed with flanges 18 which overlap the side wells ,2 0i" t ll ithin the car crest-ranged angle her corner posted?) to which the flanges 18 are secured by bolts 20. The body portion of the end sheet may he riveted to the other legs of the angle bars by rivets 21.,

The lower edge of the end sheet lt is provided with means forming horizontal stiftoning and attaching flange. For example the lower edge of the sheet may he flanged out, as indicated at 22, and riveted or otherwise secured, as at 23, to the under frame of the oer. At the upper edge of the'sheet is arranged e reinforcing member B lpreferehly an angle bar the vertical leg of'which is riveted at 25 to the end sheet. The angle her is provided preferably with angular er:- tensions or wings 26 secured to the corner posts 21.

This application is a division of my 00- pendingepplication Serial No. 99,968, filed November 8, 1913.

I claim:
